Almost 4 weeks later still no response

I followed the steps for the Buy and Get promo of SMSing the appliance model number and getting a URL. I then completed the forms and uploaded pictures of the 3 appliances. This was around 25 December. I never received any confirmation or PIN number to book the flights. I eventually get through to call centre a few days ago who say I need to resend pictures of the appliances which I did. Once again I have not received any response. <br> <br> This flight deal was a big factor in deciding to purchase Samsung products so I am a little concerned that I haven't been able to redeem the flights yet.
